Adoption DNA testing is probably one of the most frequently performed types of testing that is done. Many people who were adopted when they were young grow up with an incredible curiosity about the people who created them and the families they might have come from. When you are growing up you generally know the majority of your cousins, aunts and uncles. You hear the family stories and see the family photographs that prove to you your connection to this group of people and also what common traits you have inherited from them. You may even be aware of your genetic predisposition to have certain diseases because you know your family.

Adoption DNA testing allows the person that did not get to know all of these things about their family and their history to be able to discover these facts. Some facts such as the genetic predisposition to certain diseases will be of major importance to the individual as they will be able to inform their doctors of things they should be watching for.

Some adoption agencies require that the mother and father be tested when the baby is given up for adoption. In this way they can prove that they received the baby from the people who were the child’s legal, biological parents who had the right to give the child up for adoption. This could save the adoption agency and the adoptive family a lot of grief in the future should someone show up claiming to be the biological parent of the child and wanting to revoke the adoption.

Adoption DNA testing is usually performed on the child when they find their birth parents, in order for them to confirm they have found the correct family. This test is done by taking a saliva sample from the mouth of the individuals to be compared. Sometimes the birth parents are no longer alive for the testing to be performed and in that case the adopted person may have a sibling relationship test performed to prove they share a parent with another individual.

The sibling test can give results even if the people share only one parent. You can even prove that you share a common ancestor with a cousin or other relative that is not as close as a parent or a sibling. These tests are often performed when someone claims to be a relative of a person who is famous, rich, or high profile.
